Hazards coming on early while braking
Discussion
Hello All just looking for your opinions if this is a characteristic or potential problem? Everything feels normal with the brakes and car has only done 3.5k miles.
The hazard lights ( emergency stop feature) appear to come on early while braking firmly in my A110 GT on PS4 tyres. I can't feel the ABS kicking in and its almost like the system is set to trigger too early. Having just read the manual the hazzard light feature is meant to be disabled in Sport which I am in. I have not tried track mode yet. If I am on a twisty road they can come on every few corners under braking. When tyres and brakes are fully up to temp braking does improve as you would expect and the warning is triggered slightly later but well before ABS intervention.
Coming from Lotus's I would like a touch firmer springs and also a slightly stickier tyre which I will do in the future.
I will do more experimenting but thoughts appreciated. Do your hazards come on every spirited drive?

In a way it makes sense. Because Alpine's braking performance is really good due to lack of mass and relatively strong braking system. In most occasions an Alpine will stop in a shorter distance than the car behind. So considering that I'd say it's normal that the car goes in to hazard mode a bit earlier than expected.
Yup, despite the manual saying they shouldn't come on in Sports mode, they do. But not in track. I think it's not just a function of how hard you brake, but how quickly you get on the brake pedal. Ultimately the idea is to warn someone behind you're stopping quickly, and in a true emergency stop you'll just bang on the brakes rather than feed them in progressively.

That has been my experience. Not only in the A110, but also in my last French car, a Citroen. A ‘sudden’ breaking manoeuvre triggers the hazard lights, rather than a hard press on the pedal.
I understand why the hazards would be setup this way. But I can’t say I like it.

Just as a follow up. I looked at my brakes and the front right pads were sticking in the caliper. One was quite tricky to get out. Removed and cleaned both fronts and the brake feel is now far better. I had not realised it had changed so much. I could not get the hazards to come on without actually provoking it.

What do you mean by "sticking in the caliper"? The OEM front brake pads have a double-sided adhesive tape at the back plate, so they will stick to the piston.
Where the top and bottom of the pad backing plate run. So when the pads are freed from the piston they would not slide in and out with the pins removed. There was also minor fretting on the pins.I did not know they were stuck on at first.
